SUPPORTING ROLLER FOR KILN BARRELS AND THE LIKE Application filed February 28, 1928.

This invention relates to rollers for the engagement of tires arranged about the barrels of rotary kilns and the like to revolubly sup port the same, and while the rollers are particularly adapted to revolubly support kiln barrels they may be used for other purposes, as for supporting rotary screens, drums of concrete mixers and the like.

Rollers of this character as heretofore constructed consist of a disk like member arranged with an axial bore for the engagement of a shaft, onto which shaft the roller is forced under pressure, or the shaftinserted in the bore under pressure and keyed therein,

the rollers being rotatably supported by mounting in bearings in saddles for the engagement'of a barrel tire or riding ring extended about the barrel the weight of the barrel being taken up by the shafts through the rollers. By this arrangement the weight of the barrel imposes a stress upon the roller carrying shafts which tends to bend the shafts and even shearing off the shafts necessitating the frequent renewal of the rollers.

It is the object of the present invention to overcome the above disadvantages by constructing the rollers with the barrel supporting port-ion and the support for the rollers self-contained and of a one piece integral structure.

In the drawing accompanying and forming a part of this application, Figure 1 is an end elevation showing a roller support for the barrel of a rotary kiln only a portion of the kiln barrel being shown.

Figure 2 is an end elevation, partly insection, of my improved supporting roller for kiln barrels and Figure 3 is a longitudinal sectional view of the roller taken substantially centrally through the roller.

In the carrying out of the embodiment of the invention as illustrated in the drawing the roller is made of an integral one piece structure, preferably comprising a steel casting, and embodying a rim portion 4 the transverse face of which rim extends in a plane parallel with the axis of the roller and axial hollow trunnions 5 united with the rim by an interposed web in the form of flanges 6 Serial No. 257,617.

extending radially from opposite ends at a rlght angle to the rim and the trunnions extending outwardly from the flanges, said flanges and rim forming a hollow structure substantially of U-shape in cross section. To re-inforce the web connection of the rim with the trunnions and strengthen the roller ribs 7 are circumferentially disposed and equidistantly spaced about the roller, said ribs extending inwardly from the rim and longitudinally of the roller between the flanges terminating substantially in the plane of the inner wallof the trunnions and merged with the rim and flanges to unite the same into an integral structure. The re-inforcing ribs are in the nature of spokes uniting the rim with the trunnions through the webs or flanges 6. To reduce the weight of the roller and to also facilitate the removal of the core sand from within the roller perforations 8 are ar ranged in the webs between the ribs. To provide a smooth bearing surface for the engagement 'of the barrel tire the periphery of the rim is machined, and the periphery of the trunnions are also machined to produce a smooth bearing surface, the trunnions being arranged with a shoulder 9 at the juncture thereof with the rim connecting webs 6 for the engagement of the bearing support for the roller and hold the same against end wise or axial movement.

In Figure 1 I have shown the manner of supporting a kiln barrel 10 by my improved roller. Two rollers are utilized, indicated in a general way by R, for engaging a tire 11 extended about the barrel at opposite sides of the longitudinal axis of the barrel, the rollers being mounted in hearings in saddles 12 mounted on a guideway of a supporting frame 13 to have adjustment toward and away from the center of the barrel and arranged to be adjusted by lead screws 14. It has heretofore been the practice in order to take up'the load of the barrel to utilize two pairs of rollers to support the barrel, one pair of rollers being mounted in each saddle at both sides of the axis of the barrel. By my improved roller it is only necessary to use two rollers, one roller at each side of the longitudinal axis of the barrel as shown.

Having thus described my invention I claim:

In a support for a kiln barrel and the like, a supporting frame, a pair of roller carrying saddles adjustably mounted on said frame in predetermined spaced relation, each saddle carrying a roller, and a lead screw to adjust the saddles toward and away from each other and retain the saddles in adjusted position.

Signed at the city of New York, in the county of New York and State of New York, this 21st day of February, 1928.
